Zk 中 两列 listbox资料转移，并获得 listbox中的值

<hlayout height="160px"  width="260px">    <listbox id="candidateLb" hflex="1" vflex="true" multiple="true" rows="8">        <listhead>            <listheader label="合同成品" width="80px" ></listheader>        </listhead>            </listbox>        <vbox spacing="10px" width="24px">        <image style="cursor:pointer" id="chooseAllBtn" src="/img/rightrightarrow_g.png" />        <image style="cursor:pointer" id="chooseBtn" src="/img/rightarrow_g.png" />        <image style="cursor:pointer" id="removeBtn" src="/img/leftarrow_g.png" />        <image style="cursor:pointer" id="removeAllBtn" src="/img/leftleftarrow_g.png" />    </vbox>               <listbox id="chosenLb" hflex="1" vflex="true" multiple="true" rows="8">        <listhead>            <listheader label="已選成品" width="80px"></listheader>        </listhead>        <template name="model">            <listitem>            </listitem>        </template>      </listbox>   </hlayout>

java页面处理

public void onClick$chooseBtn() throws Exception{if(candidateLb.getSelectedIndex()<0) {MyMessagebox.info("請選中合同成品資料.");return;}String files=this.candidateLb.getSelectedItem().getValue();candidateLb.removeItemAt(candidateLb.getSelectedIndex());chosenLb.appendItem(files,files);}public void onClick$removeBtn() throws Exception{if(chosenLb.getSelectedIndex()<0){MyMessagebox.info("請選中已選成品資料.");return;}String files=this.chosenLb.getSelectedItem().getValue();chosenLb.removeItemAt(chosenLb.getSelectedIndex());candidateLb.appendItem(files,files);}public void onClick$chooseAllBtn() throws Exception{if(lstcontractno.getSelectedIndex()<0) return;chosenLb.getItems().clear();String parax=lstcontractno.getSelectedItem().getValue().toString().toUpperCase();JdbcDao dao=JdbcFactory.getDgWofeJdbcDao(plant);String sql=" select sequenceno||'.'||itemno as consumelst  from ct_t_contractitem  where class='0' AND contractid='"+parax+"'";ArrayList<LinkedHashMap> lstRet=  dao.query(sql);for(LinkedHashMap map: lstRet){chosenLb.appendItem((String)map.get("CONSUMELST"),(String)map.get("CONSUMELST"));}candidateLb.getItems().clear();}public void onClick$removeAllBtn() throws Exception{onSelect$lstcontractno();  //查询出来的所有资料chosenLb.getItems().clear();}

获得已选资料的笔数  this.chosenLb.getItems().size();

获得已选资料  （因我的资料是两个栏位合成，所有有进行字符截取）

 String sequence_no="",item_no="";
List<Listitem> list = this.chosenLb.getItems();  
if(list != null){
int index = 0;
double c =  ((double) list.size())/5;
index=(int) Math.ceil(c);
 
for(int i = 0; i < list.size(); i++){
String itemx = list.get(i).getValue();
String a[] = itemx.split("\\.");  //截取字符串
     if(i < list.size()-1){
        sequence_no+="'"+a[0]+"',";
        item_no+="'"+a[1]+"',";
     }else{
       sequence_no+="'"+a[0]+"'";
       item_no+="'"+a[1]+"'";
      }
      }
         }
